Most of the changes are centering around the Retribution tree. Some are pretty crazy, like Seal of Corruption dealing holy damage, and Divine Storm dealing physical damage. There is no indication if these changes will make it into patch 3.0.3 or arrive in a later update.
There's a couple of other changes that stick out for me.
- Seal of Command lost about 20% of it's overall damage
- Most other seals were reduced by around 13% to 21%
- Judgement of the Wise grants 15% of base mana instead of 33%
- Most other judgement effects are reduced by about 15%
- Art of War was retooled to increase damage of Judgement, Crusader Strike, and Divine Storm instead of increasing critical strike damage
And finally, Blessing of Might now increases AP by 306. It used to be 305. So it's not a total nerf...
